Product Description
This circular fisheye lens produces circular images with an angle of view of 180? when attached to a full-frame digital SLR or 35mm film SLR camera. It has a fast maximum aperture of F3.5 and a minimum focusing distance of 13.5cm (5.3"). Sigma's super multi-layer coating and Special Low Dispersion (SLD) glass provide excellent image quality for digital and film SLR cameras. The special fisheye design allows maximum creative expression.This circular fisheye lens produces circular images with an angle of view of 180?and also incorporates an auto focus system to achieve accurate focusing that might be difficult through the camera's viewfinder due to the extremely large depth of field. This lens is perfectly suited for low light conditions indoors or at dusk.This circular fisheye lens has a minimum focusing distance of 13.5cm (5.3") and a maximum magnification of 1: 4.6 making it particularly useful for close-up photography. Special Low Dispersion (SLD) glass offers effective compensation of color aberration. Sigma's super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific applications such as solid angle measurements of cloud distribution over the sky, or vegetation distribution of the rain forest canopy.Similar Products

Disclaimer: I only have a second hand 8mm/f4, without DG. Use it on 5D.
Pro:
1. Fun factor. There is nothing like it on a full frame such as 5D. This lens rules!
2. Light weight, compact, extremely smooth MF ring! The lens cap is of great design and quality, smooth, secure, and firm, period!
3. Surprisingly low color fringe and flair when light source is in or around the frame.
4. Very short close focus distance.
Neutral:
No HSM, AF can get lost - quite understandable though, for a lens THIS WIDE.
Con:
So so sharpness over all. Very good around F8 - F10. But not too bad wide open either, unlike the Sigma 20/f1.8 and 24/1.8 I have - these two primes are awful wide open at F1.8, but immediately get better stop down (probably a market trick to lure buyers away from Canon's more conservative F2.8 primes).
Bottom line:
This is fun unlike anything else. Full frame at 8mm + 180 degree view angle - sweeeet! I heard the newer f3.5 DG is far better in IQ department. But my fisheye is for fun really, the distortion and the covering all/missing none effect, so pxiel level sharpness is not the most important thing for me here. Besides, I got my F4 copy for $450, what a deal! Just love it! Just be careful with the front element since it can focus so close to the nearest subject...

I have had this lens for some time and find it to be quite a bit of fun. It is a quirky world view giving you 180 angle of view and full circle image on full frame sensors (Your feet will be in many photos!). It is super close-focusing (you can nearly touch the subject with the front element!), and VERY sharp. Of course there is a lot of distortion (it is supposed to be there!) and you must edit all images. I would love to find a Photoshop action to automate this process as it does discourage my use of it somewhat. The lens itself is QUITE small, but solidly built as are most Sigma "EX" lenses. I often throw this lens into the bag on any outing as it can provide some creative outlet not possible with other lenses, and get me to think outside the box. My only niggle with the lens (and if I could I would rate it 4.5) is that is not internal focusing and I am always surprised to feel the front element spinning when focusing. The lens is TINY so a bit of bulk for an IF design would not hurt its usability much. Highly recommended.

Great lens, but has blue chromatic aberration on the edges of the circle, easily fixable in photoshop. I loved it for my Canon Rebel xti (cropped cirlcle due to cenversion factor), now I love it even more for my Canon 5D Mark II ( full circular fisheye ). Great lens for special effects, not everyday use.
By D. Burbank (Ithaca, New York)
I own an excellent selection Canon "L" lenses. But I was ready to try to fisheye. After extensive research, I decided to give the Sigma 8mm f/3.5 EX DG Circular Fisheye a try. I'm glad I did. This lens feels good, it's small (compared to my "L" lenses), it focuses fast and quiet. The photos it takes are outstanding. I have even stated using the Fisheye-Hemi Photoshop plug-in to manipulate the images and "straighten" them out a bit. I recommend this lens!

This Sigma lens is like a working piece of art. The build quality is high, the images are bright and sharp with excellent color saturation. I use mine to shoot full-screen 360 by 180 panoramas and the results are breathtaking! The best part is that this lens costs 1/3 to 1/4 of what the Canon 8mm lens costs. It's an awesome deal, no matter what way you look at it. The Sigma 8mm is definitely a professional grade lens.
